Codes (High Voltage Method) table. In addition, when

verifying sector protection, the sector address must appear

on the appropriate highest order address bits. Refer to the

corresponding Sector Address Tables. The Command

Definitions table shows the remaining address bits that are

don't care. When all necessary bits have been set as

required, the programming equipment may then read the

corresponding identifier code on I/O7 - I/O0.To access the

autoselect codes in-system, the host system can issue the

autoselect command via the command register, as shown

in the Command Definitions table. This method does not

require VID. See "Command Definitions" for details on

using the autoselect mode.

Autoselect Mode

The autoselect mode provides manufacturer and device

identification, and sector protection verification, through

identifier codes output on I/O7 - I/O0. This mode is primarily

intended for programming equipment to automatically

match a device to be programmed with its corresponding

programming algorithm. However, the autoselect codes

can also be accessed in-system through the command

When using programming equipment, the autoselect mode

requires VID (11.5V to 12.5 V) on address pinA9. Address

pins A6, A1, and A0 must be as shown in Autoselect
